Geochemical Modeling - Idaho National Laboratory
Geochemical models for the eastern Snake River Plain aquifer system are being used to better understand the flow of groundwater beneath the INL and, ultimately, to better understand the fate and transport of radiochemical and chemical constituents. As water moves through the ground, it picks up chemicals from the gases and rocks it comes in contact with.
Developing Geological Framework - Idaho National Laboratory
As basaltic lava cools and hardens, the inclination, declination, and polarity of the Earth’s ambient magnetic field is recorded in the magnetic minerals of the rock. The recorded magnetic values are largely preserved and can be deciphered by paleomagnetic analysis.
Drilling and Coring - Idaho National Laboratory
We drill and maintain wells around the INL to monitor and sample groundwater, obtain basalt and sediment cores for study and analysis, and study the physical properties of the subsurface (geophysical logging).
This information helps us to improve the scientific understanding of the eastern Snake River Plain and its aquifer. In particular, we are examining the subsidence of the plain and...
Video Logging - Idaho National Laboratory
Drillers use the vertical and horizontal views captured by our downhole video camera to examine borehole integrity before placing water well casing, well screens, and submersible pumps. Hydrologists and geologists use the images to verify geophysical data such as: changes in rock type, small-scale geologic structures, rock fractures, and groundwater movement.
Geophysical Logging - Idaho National Laboratory
Our scientists collect geophysical data from wells to understand the character of rocks and fluids below the surface. Geophysical data for a well are recorded, interpreted, and then disseminated as a geophysical log. Engineers and well drillers use geophysical logs to make well construction decisions such as design for well casing, well screen, and pump placement. Hydrologists, geologists and...
Water Archive Library - Idaho National Laboratory
Since 1966, we have archived over 6000 samples of about 500 mL each of "raw" (unfiltered and unpreserved) water from groundwater and surface-water quality sites collected during our monitoring activities. Through the years, we've kept the water samples in a secure room and tracked which samples researchers have requested and analyzed for various projects.
Contact us for more information...
Core Storage Library - Idaho National Laboratory
Our Core Storage Library currently houses about 73,000 feet of core and several suites of cuttings from boreholes drilled at the INL. More cores and cuttings are added every year. The CSL also houses two suites of core and cuttings from the western Snake River Plain. In 2015, we added new core storage space in building CF 674. We recently...
Geophyical Logging and Water-Quality Assessment for Project Hot Spot
Relatively little is known about the Yellowstone-Snake River "hotspot" system. To increase our knowledge, the U.S. Department of Energy’s Geothermal Technologies Program provided over $4.5 million of this $6.7 million project using American Recovery and Reinvestment Act funds.
Hydrologic Investigations near the Remote Handled Low-Level Waste Facility
The U.S. Department of Energy has proposed a location for a new facility to store waste at the INL. In the unlikely event that waste leaks from the facility, it will be important to monitor whether the contamination reaches the aquifer and baseline information is need before the facility is built.
Because we need to know how water and contaminants may travel through the aquifer, we need...
Naval Reactors Facility Groundwater-Quality Monitoring
As part of the Comprehensive Environmental Response Compensation and Liability Act, it is important to evaluate the effect of Naval Reactors Facility (NRF) activities on the water quality of the eastern Snake River Plain aquifer.
Wood River Valley Groundwater-Flow Model
Rapid population growth in the Wood River Valley since the 1970s has caused concern about the long-term sustainability of the groundwater resource. Water-resource planners and managers, as well as other decision makers, need a tool for water rights administration and water-resource management and planning.
Microplastics in Urban Streams of the Northeast Region
Microplastics in the environment are of increasing concern among resource managers and ecologists. With global production of plastic topping 300 million metric tons in 2015, research in fresh and marine waters throughout the world has implicated urban runoff, wastewater treatment effluent, and litter breakdown as major sources of microbeads and synthetic pieces and fibers that are slow to...
The USGS collects, analyzes, and distributes data on a wide variety of water-related issues and resources. Much of our data is publicly available through the National Water Information System (NWIS), but additional datasets and analytical tools are also available.
